This invention relates to a dyeing apparatus. The object of theinvention is the production of dyeing apparatus with which hats or otherobjects are dyed the same color and shade, by 5' maintaining them at alltimes during the operation of dyeing in the dye liquor. This conditionis secured by dyeing said hats or objects in an operating tank havingcovers, the operative positions of which can be easily adjusted.

The second object of the invention comprises means wherewith thedirection of the ow of the dye liquor can be reversed and therebyefficiently penetrate the hats or other objects operated upon.

The third object of the invention is the production of means wherewithany fumes generated during the process of dyeing can easily escape.

In the accompanying drawing Fig, 1 represents a top plan View of thedyeing apparatus and Fig. 2 shows a section of Fig. 1 on the line 2, 2.

The dyeing apparatus comprises the conical oval shaped dye liquorreversing container designated in its entirety by the numeral 28. Thesaid container is indicated having the conical oval shaped wall 2l,with'the flange 22 at its upper end, and the lower portion of the wall2l joins with the fiat bottom 23. Drain piping 24 with the outlet valve25 extends from the wall 2l. Journal brackets 28, which may be providedwith stuffing boxes, are indicated with the journal bearings 29, Thelatter are fastened to the outer face of the wall 2i diametricallyopposite each other. A bed plate 38 supports the journal brackets 28. Afoundation 32 having the longitudinal gutter 33 and the cross gutter 34supports the bed plate 38. The drain piping 24 leads to the gutter 34.An electric motor 38 having the armature shaft 39 is supported upon thebed plate 39. A directional relay 49, shown only diagrammatically, isprovided for the electric motor 38. A propeller shaft 42 extends throughthe journal bearings 29 and has fastened thereto the propeller 43.

An operating tank is designated in its entirety by the numeral 5D. Thetank 50 comprises the 7 bottom wall 5|, having a plurality ofperforations 52. The wall 5l is supported upon and fastened to theflange 22. An oval shaped vertical wall 54 is supported upon the wall 5land the angle iron 55 connects the walls 5| and 54 and the flange 22.50' At the upper end of the wall 54 is indicated thereturn shaped flange58, and the angle iron 59 is interposed between the wall 54 and the saidflange 58 and fastened thereto.

A top cross wall is indicated at 60 with the opening 6|. A vent-funnel62 extends up from the wall 80 over its opening 6l. The upper end of thefunnel 62 is provided with the reinforcing band 63, and from the latterextend eyelets '54. To each of the latter is fastened one end of asupporting chain 85. Angle irons 61 extend crosswise upon the cross.wall 80 and are fastened thereto. The cross wall 68 is fastened to thetop of the tank by means of the bolts 68.

To the cross wall are hinged a pair of outer covers, each designated inits entirety by the numeral 10, by means of hinge connections 1|. Eachof the covers 19 has extending therethrough an opening 12, and hasformed therewith a plurality of depressions 13 to form strengtheningribs. A pair of handles 14 extend up from each outer cover 18, and eachof the latter is strengthened with the angle iron 15. From the outerface of each of the covers 19 extends a ,supporting hook 18 and the forkshaped clamping hook 19. From the bottom face of each cover 10 extend apair of journal brackets 83. v

A pair of intermediate or inner suspended covers are each indicated inits entirety by the numeral 85. Each of the covers on its inner side isprovided with the upwardly extending curved portion 86 having the edge81. The said edges 81 are spaced from each other to form a vent opening88. The curved portions 8B are provided to prevent injury to the objectsdyed when the covers 85 are moved to different positions. TheA outer endof each cover 85 is indicated at 89. An Veye bolt extends up from eachcover 85 adjacent to its outer end.

From the upper face of each cover 85 extend a pair of journal brackets92.

Four links are each indicated at 95. Each of said links has its upperend inv hinged connection with one of the journal brackets 83 by meansof the pin 93 and its lower end is hinged to one of the journal brackets92, by means of the pin 94.

It will be noted that the pins 94 are closer to the vertical axis of theapparatus than the pins 93, and thereby the links 95 are positioned ininclined positions, when the inner covers 85 are in their operativepositions. By reason of the centers of the pins 93 being horizontallyspaced from the centers of the pins 94 ltoward the outer ends 89 of thecovers 85, the said covers are forced `to position said ends 89 to bearagainst the inner end face portion of the wall 54 of the operating tank58. By this means there is prevented any considerable leakage betweenthe said ends 89 and the adjacent face of the wall of the operating tank50.

A chain 98 extends from each eyebolt 90, leads through the adjacentopening 'l2 in its cover 10. The chains 96 are adjustably clamped indifferent positions in the adjacent forked shaped clamping hooks 19 totilt the covers 85 to different positions.

To operate the dyeing apparatus the outer covers 'l0 are lifted to theirvertical positions as indicated in dotted lines at 10a, by means of thehandles 14, and are held in place by connecting the supporting chains 65to the supporting hooks 18. By this means the inner covers 85 are alsolifted to their raised positions as indicated in dotted lines at 85a.

The operator then charges the operating tank 50 with the hats or otherobjects to be dyed, and

dye liquor to about the level of the line is.

poured into the apparatus. The dye liquor will iiow to the reversingcontainer 20 through the perforations 52 of the wall 5i. Next the coversl!) and 85 are lowered as shown in full lines in Fig. 2. The electricmotor 38 is now started, by means of which the propeller 43 is turnedand the dye liquor ilows from the container 20 to the op` erating tank50, through the perforations 52 at one side of the wall in the directionof the arrows |05, and penetrates the hats or other objects to be dyedin the said operating tank 50 to dye the same. The dye liquor returns tothe reversing container 20 at the opposite side thereof.

The circulation of the dye liquor from the container 2G to and throughthe operating tank 5D is repeated for a predetermined number of times.The rotation of the electric motor 38 is then automatically reversed bythe directional relay 45, by means of which the propeller 43 is turnedin the reverse direction for a predetermined number of times. The dyeliquor no-w ows in the direction reverse to that shown by the arrows m5,and the hats or other objects are again penetrated by the dye liquor.The

i electric motor 38 by means of the relay 4|) is then reversed to itsoriginal direction and the steps are repeated until the hats or otherobjects are thoroughly penetrated and dyed.

If it is desired to drain the apparatus the outlet valve 25 is openedand the dye liquor Will flow through the drain pipe 24 into the crossgutter 34 and then will be discharged into the longitudinal gutter 33 toa tank or other container as desired.

Attention is called to the fact that the hats 0r other objects dyedremain at all times during the dyeing in the operating tank 50completely immersed in the dye liquor in said operating tank, to securethe same reaction with the dye liquor to dye all the hats or otherobjects the same shade and color. In case the level of the dye liquorfalls below the level indicated at |00 and below the level of the innercovers 85, the operator lowers said covers 85 by lifting the chains 96from the fork shaped clamping hooks 19 and lowers the said inner covers85 to a position as indicated at 85a, to maintain all the hats or otherobjects below the top level of the dye liquor in this position as wellas in the original position of the inner covers 85, the suspension ofsaid covers 85, by the links 95 tends to position the ends 89 of thecovers against the inner end faces of the wall 54. The vent opening 88between the edges 8l of the inner covers 85, the opening 6| and the ventfunnel 62 permits the escape of any fumes generated in the apparatus.

Various modifications may be made in the invention and the presentexemplication is to be taken as illustrative and not limitative thereof.

Having described my invention, I claim:
